FIELD OF THE INVENTION

This invention generally relates to shelving systems, and more particularly to shelving systems which incorporate one or more pusher assemblies thereon.

BACKGROUND OF THE INVENTION

Pusher assemblies are generally known in the art as a viable way to automatically front face product in a variety of settings. While pusher systems are typically employed in the conventional retail environment for facing cosmetic items, etc., they may also be utilized refrigerated cases or the like. An exemplary embodiment of such a pusher assembly may be seen at U.S. patent application Ser. No. 13/288,058 filed on Nov. 3, 2011, assigned to the instant Assignee and herein incorporated by reference in its entirety.

Walk-in coolers, which may be employed in the food service setting to store bulk food supplies for later preparation, or be employed in the warehouse setting for the storage of refrigerated or frozen goods, etc., typically employ a rack system therein. Unfortunately, the conventional pusher assembly is not readily configured to mate with the rack system of a walk-in cooler. As a result, one must either forego the use of a pusher assembly and its attendant advantages of front facing product toward a leading edge of a shelf, or alternatively undergo a complex retrofit of existing shelving to ensure that it will adequately and securely receive a pusher assembly. Therefore, there is a need in the art for a pusher assembly rack system that may be readily employed in the context of a walk-in cooler or otherwise.

The invention provides such a pusher assembly rack system. These and other advantages of the invention, as well as additional inventive features, will be apparent from the description of the invention provided herein.

DETAILED DESCRIPTION OF THE INVENTION

Turning now to the drawings, an exemplary embodiment of a pusher assembly rack system is shown at FIGS. 1-12. With specific reference to FIG. 1, the pusher assembly rack system 20 includes a frame-like rack structure 22 herein referred to as rack 22, with a plurality of pusher trays 24 installed thereon. As will be explained in greater detail below, the current configuration shown in FIG. 1 advantageously allows for one or more pusher trays to be employed in a rack system within environments such as walk-in coolers or the like. Such a configuration also advantageously allows for the lateral adjustment of pusher assemblies 24 relative to rack 22 for customization purposes. Additionally, and as will also be explained in greater detail below, each pusher assembly 24 is longitudinally held in place relative to rack 22 to provide a stable mounting for the pusher assembly 24. Rack system 20 shown in FIG. 1 may be readily employed in environments such as walk-in coolers or the like, storage and front facing of bulk goods. However, it would be readily recognized by those skilled in the art that the teachings of the invention herein may be applied to other context not limited to walk-in cooler-type environments.

As stated above, rack system 20 includes a rack 22 with a plurality of pusher trays 24 mounted thereto. All four pusher trays 24 are shown on an upper-most shelf of rack 22, and four pusher trays 24 are shown on a lower-most shelf of rack 22. It will be readily recognized that fewer pusher trays 24 may be included on any of the shelves of rack 22. Furthermore, the number and location of the shelves shown in FIG. 1 is not in any way limiting on the invention. Fewer or greater shelves may be utilized, and they may be situated at various locations along rack 22.

Rack 22 includes a plurality of vertical supports 26 which are generally spaced apart at the four corners of a rectangular pattern. A plurality of shelves in the form of wire support frames 28 (also referred to herein as wire racks) are supported by vertical supports 26. The location of wire support frames 28 may be readily reconfigured as described below. Each pusher tray 24 is configured to carry a linear row of products 30 as schematically represented in FIG. 1. As is generally understood by those skilled in the art, each pusher assembly 24 is operable to bias the linear row of products 30 (i.e. from right to left or along direction 32) towards a front edge of each wire support frame 28. This ensures that products 30 carried by pusher trays 24 are situated at the front edge of wire support frame 28 to provide easy access thereto.

Turning now to FIG. 2, wire support frame 28 will be described in greater detail. Wire support frame 28 includes an outer peripheral wire 40 of a generally rectangular shape. A plurality of lateral wire members 42 are connected to and extend between longitudinally extending edges of outer peripheral wire 40. Each of lateral wires 42 are situated parallel to front and back edges of outer peripheral wire 40 as illustrated. A pair of rack connection elements 44 are mounted to an underside of wire support frame 28. Rack connection elements 44 allow for the rapid installation of wire support frame 28 to vertical supports 26. (See FIG. 1). Each connection element 44 includes front and rear forwardly extending connection pins 46 for mounting wire support frame 28 to vertical supports 26.

More specifically, and turning now to FIG. 3, each vertical support 26 includes a plurality of slots 52 formed through a back wall 54 of each vertical support 26. It will be recognized that in the view shown in FIG. 3, a portion of outer peripheral wire 40 of upper and lower-most wire support frames 28 has been removed to expose the ends of lateral wire members 42 to illustrate the mounting configuration of each pusher assembly 24 relative to wire support frame 28. Also shown in FIG. 3 is the interaction between front and rear connection pins 46 of each connection element 44 relative to supports 26. Taking as an example upper-most wire support frame 28, it can be seen that the front-most connection pin 46 (i.e. connection pin shown on the right-most side of the illustration of FIG. 3), is received one of slotted openings 52 of vertical support 26. The same configuration is true for the rear-most connection pin 46 of the upper-most wire support frame 28 shown in FIG. 3. Although not illustrated, connection element 44 situated on the other side of the upper-most wire support frame 28 shown in FIG. 3 exhibits an identical mounting configuration with vertical supports 26.

As can also be seen from FIG. 3, each vertical support 26 includes a plurality of slotted openings 52 which are arranged in two linear rows. Each wire support frame 28 is positionable in any one of slotted openings 52 to provide clearance for different heights of products carried by rack system 20.

Turning now to FIGS. 4-12, and particularly FIG. 4, pusher assembly 24 will be described in greater detail. Pusher assembly 24 includes a base structure 60 and a pair of moveable side barriers 62 (See also FIG. 5) which are mounted to base structure 60 and moveable relative to base structure 60 along directional axis 64. Such adjustment capability allows for pusher assembly 24 to accommodate product of differing widths, which may include retail merchandise of a greater width than the width of base structure 60. Pusher assembly 24 also includes a pusher 66 mounted to base structure 60 and moveable relative thereto along directional axis 68. As described above, pusher 66 is operable to bias a linear row of product 30 forward, i.e. along directional axis 68 from right to left FIG. 4.

Base structure 60 includes a pair of support bars 70. Support bars 70 are in an opposed-spaced relation as shown in FIG. 4. Each support bar 70 includes a connection portion 72, which as will be described in greater detail below, permits for the connection of pusher assembly 24 to the remainder of rack system 20. Each connection portion 72 includes a forwardly opening notch 74, a downwardly opening notch 76, and a shoulder 78. Each of the aforementioned elements contacts one of lateral members 42 shown for example in FIGS. 1 and 2 and discussed below.

Base structure 60 also includes a wire support frame 86 (See FIG. 5) mounted generally on top of support bars 70. Wire support frame 86 include a plurality of longitudinally extending wires 88, commonly connected to front and rear laterally extending wires 90 as shown. Base structure 60 also includes a pair of support elements 92 positioned between support bars 70. As described in greater detail below, support elements 92 receive portions of side barriers 62, and allow for the adjustment thereof relative to base structure 60. It will be recognized that only a single side barrier 62 is illustrated in FIG. 4 for purposes of clarity.

Turning now to FIG. 5, pusher assembly 24 is shown in a perspective view. As can be seen in this figure, pusher assembly 24 also includes a removable front stop 94 which may also incorporate additional structures such as a label holder 98. Front stop 94 is received on upturned ends 96 of outer-most longitudinally extending wires 88. Each side barrier 62 includes a divider 102 and front and back wire extension elements 104. The front-most wire extension element of each side barrier 62 passes through apertures 106 formed in support bar 70 and extends into passages 108 of the front-most support element 92 which are aligned with apertures 106. The same mounting configuration exists for the rear-most wire extension elements 104 shown in FIG. 5 relative to the rear-most support element 92 shown therein.

Turning now to FIG. 6, front-most support element 92 will be described in greater detail with particular attention made to its interaction with side barrier 62. It will be recognized that the following description applies equally well to rear-most support element 92, and for purposes of brevity, such an additional description is not provided. As stated above, support element 92 includes passages 108 which align with apertures 106 formed in support bar 70. The front-most extension wire 104 of each side barrier 62 extends into passages 108 through apertures 70. Each support element 92 also includes a rotatable pin 110 with a tension clip 112 depending therefrom. Each rotatable pin 110 is positioned between passages 108.

Turning now to FIG. 7, the aforementioned configuration is shown in cross-section at FIG. 7 relative to the left-most tension clip shown in FIG. 5. Pin 110 is received in collar 116 of each support element 92. Tension clip 114 includes a generally hook-shaped end which extends into an exposed portion 114 of each passage 108 to clamp against wire extension element 104 received thereby. This clamping force restricts movement of wire extension element 104, and thus its respective divider 102, relative to base structure 60. As a result, tension clips 112 function to lock each side barrier 62 in its adjusted position. Turning now to FIG. 8, a similar cross-section taken through the right-most tension clip shown in FIG. 5 is illustrated therein. As shown in this view, tension clip 112 includes a hook portion which depends inwardly into an exposed portion 114 of passage 108 to provide a clamping force against wire extension element 104 to restrict movement thereof relative to passage 108. Each tension clip 112 may be readily unsnapped from its connection to its respective wire extension element 104 to allow for the adjustment of side barrier 62. Once adjusted, tension clips are snapped once again through exposed portion 114 against wire extension element 104 received thereby to lock side barrier 62 in place.

Turning now to FIG. 9, each support element 92 includes shoulders 118 which extend into apertures 106 to fix the position of support element 92 relative to support bar 70. Additionally, pin 110 may also include a shoulder 120 which extends through an aperture 122 formed between apertures 106 for additional mounting purposes. Additionally, a pin or other fastener may extend through aperture 120 into support element 92 to provide additional mounting thereof.

Turning now to FIG. 10, pusher 66 will be described in greater detail. Pusher 66 includes a generally upright wall 124 which defines a contact face 126 which will contact a rear-most one of a row of product 30 (See FIG. 1). A plurality of notches 28 are formed proximal a bottom region of wall 124. Notches 128 receives longitudinal wires 88 of wire support frame 86 of base structure 60. Longitudinal wires 88 are freely slideable relative to notches 128 to promote the smooth movement of pusher 66 relative to base structure 60. An opening 130 is formed between the two inner-most notches 120 through which an uncoiled portion of a coil spring 132 extends. This uncoiled portion 132 may connect to a front portion of pusher assembly 24, e.g. the front-most lateral wire 90 of wire support frame 96. Other connection points are possible which will result in the coil spring 130 attempting to recoil itself into pusher 66 causing pusher 66 to move forward towards the point of connection of spring 132 to pusher assembly 24. Turning now to FIG. 11, a rear side of pusher 66 is illustrated. As shown in this view, the remainder of spring 132 is shown in its coiled configuration supported by a bottom wall 140 of pusher 66. Additionally, pusher 66 may include a locking arm 142. Locking arm 142 includes two hook portions 144 which lock against rear-most lateral wire 90. Such a configuration advantageously allows pusher 66 to be locked in place for purposes of loading product into pusher assembly 24.

Turning now to FIG. 12, the process of installing pusher assembly 24 relative to wire support frame 28 will be described in greater detail. As shown in this view, only lateral wire members 42 are shown for purposes of clarity. To install pusher assembly 24, forwardly opening notch 74 is aligned with the left-most lateral wire member 42. Pusher assembly 24 is then moved generally along direction 150 until lateral wire 42 is fully seated in forwardly opening notch 74 as shown. Thereafter, pusher assembly 24 is rotated about the left-most lateral wire 42 generally in rotational direction 152 until downwardly opening notch receives the lateral wire member 42 positioned between the left and right-most lateral wire members 42 of FIG. 12. Simultaneously, shoulder 78 makes contact with right-most lateral wire member 42 to fully seat pusher assembly 24 on rack 22. Referring momentarily back to FIG. 1, such a mounting configuration allows for the lateral adjustment of pusher assembly 24 relative to rack 22 along wire support frame 28. Such a configuration is particularly advantageous where it will be necessary to ensure there is enough clearance for later adjustment of side barriers 62 to accommodate wider product. Despite this lateral adjustment, pusher assembly 24 is fixed longitudinally relative to rack 22 to prevent movement thereof generally along direction 32 relative to rack 22. As a result, a stable configuration is achieved.

As described herein, embodiments of the present invention advantageously provide a pusher assembly rack system that may be readily implemented in walk-in coolers or other areas it is desirable to incorporate one or more pusher assemblies on a rack-style shelving unit.
